[ 1 ] - Synthesis, Characterization and Antibacterial Activity of some Novel Thiosemicarbazides, 1,2,4-Triazol-3-thiols and their S-substituted Derivatives

The thiosemicarbazides 3a-c were appeared by reaction of the corresponding substituted hydrazides 1a-c with allylisothiocyanate 2. Synthesis of some novel 1,2,4-triazole-thiols 4a-c bearing a pyridyl unit using 1-(x-picolinoyl)-4-allyl-thiosemicarbazides (x = 2,3,4) in an alkaline solution, is reported. Also, the S-alkylation of triazole derivatives 5-7a-c is described. The structure of the syn...

[ 2 ] - Simple Synthesis and Biological Evaluation of Some Benzimidazoles Using Sodium Hexafluroaluminate, Na3AlF6, as an Efficient Catalyst

Considerable attention has been focused on the synthesis of benzimidazoles due to having a broad spectrum of biological activities such as anti-parasitic, fungicidal, anti-thelemintic and anti-inflammatory activities. As a part of our research work in this area, a series of benzimidasole derivatives (3a-n) were synthesized in good to high yields by reaction of o-phenylenediamine and different a...

[ 3 ] - Synthesis and Solution Complexation Studies of a new Schiff base Ligand

A new Schiff base ligand, 2,2'-{pyridine-2,6-diylbis[nitrilo(E)methylylidene]}bis(4 bromophenol),has been synthesized by reaction of the 2,6-diamino pyridine with 5-bromo salicylaldehyde at ethanolunder refluxing. The structure of the synthesized compound resulted from the IR, 1HNMR, MS andUV spectroscopy and elemental analysis data. Formation Constant (kf) value of it’s complexes withCu2+, Ni2...

[ 4 ] - A One-Pot Synthesis of Some Novel Ethyl 2-((1H-Benzo[d]imidazol-2-ylamino)(Aryl)methylthio)acetates by Nano-CuY Zeolite as an Efficient and Eco-Friendly Nanocatalyst

A one-pot multicomponent reaction of aryl aldehydes, 2-amino benzimidazole and ethyl 2-mercaptoacetate is described as an efficient and environmentally method for the synthesis of some novel ethyl 2-((1H-benzo[d]imidazol-2-ylamino)(Aryl)methylthio) acetates in the presence of nano-Copper Y Zeolite (NCZ) as a catalyst in ethanol at room temperature. After optimizing of r...

[ 7 ] - Ni@Zeolite-Y Nano-Porous: Preparation and Application as a High Efficient Catalyst for Facile Synthesis of Quinoxaline, Pyridopyrazine, and Inadoloquinoxaline Derivatives

In this research, by a simple and modified method, nanoporous of Ni(II) ion loaded Y-type zeolite (NNZ) was designed and applied as a novel highly efficient catalyst for the synthesis of quinoxalines, pyrido[2,3-b]pyrazines, and indolo[2,3-b]quinoxalines 3a-s. These heterocycles were obtained through a one-pot condensation reaction of aryl-1,2-diamines with 1,2-dik...

[ 8 ] - تثبیت یون‌های نیکل بر روی نانومزوحفره SBA-15 و کارایی کاتالیزگری آن در تهیه‌ی ۲-آریل بنزایمیدازول‌ها در شرایط بدون حلال

در این مطالعه، نانوذرات SBA-15 با 3-کلروپروپیل تری اتوکسی سیلان و سپس با لیگاند آلی تیوکربوهیدرازید (SBA-15@ TCH) عامل‌دار شد. سپس یون‌های نیکل استات بر روی نانوبستر سیلیکاتی تثبیت گردید (SBA-15@Ni/TCH). نانوذرات تهیه شده به عنوان یک هیبرید آلی-فلزی با استفاده از روش‌های FT-IR و SEM، TEM، ,XRD EDX و BET مورد بررسی و شناسایی قرارگرفت. نانوذرات SBA-15@Ni/TCH به عنوان نانوکاتالیزگری کارامد و ناهمگ...
